sired, and as before stated the wear on the a resiliently supported reciprocable memouter surface of: the plunger may be taken up by turning the screw 1% to force the conical member 17 into the cylinder 8 in order to spread its walls. In this manner also the friction may be regulated between the two friction members and a greater or lesser friction may be attained as desired.

From the above description taken in connection with my drau-ings it will be readily apparent that I have provided an improved device which \\\'ill fullil the conditions and .t'unctio'ns of a comparatively perfect -loot warmer of this character.
